how long in copper?

[LauraCline]

I'm treating my emporer angel in coppersafe for ich. Tomorrow will be the 12th day, how long should I treat him? He will be staying in QT until the tank runs fallow for 6 weeks.

to be sure the parasites have completed the life cycle i would leave the tank fishless for 8 weeks min. 6 week copper tx should be enough to cure your fish.
